## AI interpretation — verify before relying

ONNX Runtime is a performance-focused inference engine that executes Open Neural Network Exchange (ONNX) models across Windows, macOS, and Linux.

Verdict: onnxruntime is a production-grade, actively maintained inference engine with no known vulnerabilities, permissive licensing, and broad platform coverage. Medium install friction is typical for compiled ML runtimes. Suitable for deploying ONNX models in production environments.
